The transformation rule \((x,y) \to (-x,-y)\) reflects the point across the origin. This is equivalent to rotating the point 180 degrees around the origin.
Therefore, the correct answer is:
B. it will be rotated 180 degrees.
How will the following transformation rule move a preimage?
(x,y)-(-x,-y)
A. it will be dilated to become smaller
B. It will be rotated 180 degrees
C. it will be translated up to the right
